    What is the Difference between Bluetooth Module and Bluetooth Low Energy Module?

    Bluetooth Module: Traditional Bluetooth modules support the Classic Bluetooth (BR/EDR) protocol, making them suitable for applications that require high-speed transmission or long-range communication. They are commonly used in audio devices, data exchange, and similar scenarios.

    藍牙模組 (藍牙低功耗): Designed specifically for low-power devices, BLE is ideal for low-bandwidth, low-power applications, such as smartwatches, health trackers, 和物聯網設備. It is typically used in bluetooth le sensor. Compared to Classic Bluetooth, BLE has a shorter communication range and slower data transfer speed, but it offers significant advantages in terms of low-power design.
